Fact Check

If you have a web page that reviews a claim made by others, you can include a
ClaimReview structured
data element on your web page. This element enables Google Search results to show a summarized
version of your fact check when your page appears in search results for that claim.

Example

Imagine a page that evaluates the claim that the earth is flat. Here is what a
search for "the world is flat" might look like in Google Search results if the page
provides a ClaimReview element (note that the actual visual design may change):

Guidelines

In addition to general guidelines
that apply to all structured data markup, these additional guidelines apply to fact checks:

Fact checks associated with news articles can be shown in either News results or the
combined search results view; all other fact checks can appear only in combined search results view.

Fact checks are not guaranteed to be shown:
inclusion of fact check elements in Google Search results is determined programmatically.
Fact check elements are scored based on a programmatic ranking of the site. Sites are
evaluated in a process similar to page ranking: if the site
ranking is high enough, the fact check element can be displayed in search results along with
your page.
The entire process is conducted programmatically; human intervention only occurs when user
feedback is filed as violating the
Google News Publisher criteria for fact checks,
general
guidelines for structured data, or when the publisher (whether or not a news site) does not
meet standards for accountability and transparency, readability or site misrepresentation as
articulated in our
Google News General Guidelines.

A single page can host multiple ClaimReview elements, each for a separate claim (see below).

If different reviewers on the page check the same fact, you can include a
separate ClaimReview element for each reviewer's analysis (see below).

The page hosting the ClaimReview element must have at least a brief summary
of the fact check and the evaluation, if not the full text.

You should host a specific ClaimReview on only one page on your site. Do
not repeat the same fact check on multiple pages, unless they are variations of the same
page (for example, you can post the same ClaimReview on the mobile and desktop
versions of a page).

Posting multiple fact checks on a page

Multiple ClaimReview
elements on a single page do not need to be about the same claim, but they should all be
relevant to the main topic of the page.

Most sites implement multiple fact checks per page in one of two ways:

Create a summary page with multiple summarized fact checks, each with its own ClaimReview
element. Post the full-text version of each fact check on its own page.
Each ClaimReview element on the summary page points to the full-page version
rather than to the summary page.

OR

Create a single page with multiple full-length reviews, each with an HTML anchor. Each
ClaimReview element points to that summary_page.html#anchor.

On mobile devices only, if a page hosts multiple ClaimReview elements,
all items will be displayed in a results carousel like this:

Structured data type definitions

The following structured data types are required to implement fact checks:

You must include the required properties for your content to be eligible for display as a rich result.
You can also include the recommended properties to add more information about your content,
which could provide a better user experience.

The assessment of the claim. This object supports both a numeric and a textual assessment.
The textual value is currently the only value shown in search results.
The numeric value is not shown, but is used to evaluate consistency of fact checks across
different sources; therefore having a numeric value may increase the chances of your
fact check being shown.

Try to design a consistent number to text rating system for all your fact checks. For example:

Link to the page hosting the full article of the fact check. If the page has multiple
ClaimReview elements, be sure that the fact check has an HTML anchor, and
this property points to that anchor. Examples:longreview.html or
summarypage.html#fact1

The domain of this URL value must be the same domain as, or a subdomain of, the
page hosting this ClaimReview element. Redirects or shortened URLs (such
as g.co/searchconsole) are not resolved, and so will not work here.

This field stores the URL of the publisher(s) and can be repeated as many times as needed
(for example, when multiple publishers spread the claim). The publisher can be a person or
organization. If the publisher is an organization, use one of the following URLs:

The URL of the page that is hosting the claim (preferred).

The homepage of the organization that is making the claim.

If the publisher is a person, use a definitive URL that provides information
about the person who is making the claim, such as the person's Wikipedia page.

Rating

The truthfulness rating assigned to ClaimReview.reviewRating, as a human-readible
short word or phrase. This value is displayed
in the fact check in search results. Examples: "True" or
"Mostly true".

If using a longer sentence, be sure that the beginning of the sentence
expresses the meaning, in case the sentence is truncated to fit the display. For example:
"Mostly true in the specifics, although the overall claim is somewhat misleading"

A numeric rating of this claim, in the range worstRating —
bestRating inclusive. Not shown, but used to evaluate the strength of this fact check across
multiple pages. Integer values recommended but not required. The closer this number is to
bestRating the more true it is; the closer this value is to worstRating,
the more false it is. Must be able to
be evaluated as a number. Example: 4
